# CATEGORY conversion
## DigestToByteBuffer

Computes the digest of the ByteBuffer on input and stores it in the output ByteBuffer. The digestTypes available are:

* MD2
* MD5
* SHA-1
* SHA-224
* SHA-256
* SHA-384
* SHA-512
* SHA3-224
* SHA3-256
* SHA3-384
* SHA3-512

## Format

Apply the Java String.format method to an incoming object. @see [Java 8 String.format(...) javadoc](https://docs.oracle.com/javase/8/docs/api/java/util/Formatter.html#syntax) Note: This function can often be quite slow, so more direct methods are generally preferrable.

## LongToByte

Convert the input long value to a byte, with negative values masked away.

- long -> LongToByte() -> java.lang.Byte


## LongToShort

Convert the input value from long to short.

## MD5HexString

Computes the MD5 digest of the byte image of the input long, and returns it in hexadecimal String form.
